hi,
Thank you for the recommendation for the coursebook. Have you ever taught the material in your real instruction to the students or adult in the construction field? I have visited the website you'd suggested and found the sample pages for the Level one and Level Two. Would you say more about the teaching application when using the books?
Appreciate your help so much.

Peggy,
The instruction builds English skills using construction tools and terminology. Each unit is taught using a method beginning with vocabulary and ending with conversation. The purpose is that each task builds upon the previous lesson. The method creates consistency while combining grammar tenses and requires students to listen, speak, read, and write. There is a test at the end of each chapter.

Many construction companies are hiring ESL teachers within their area and are currently using this curriculum on their construction sites.
